The rhinal cortex is the cortex surrounding the rhinal fissure, including the entorhinal cortex and the perirhinal cortex. It is a cortical region in the medial temporal lobe that is made up of Brodmann areas 28, 34, 35 and 36.

What is the function of rhinal cortex?

Hence, the rhinal cortex is well-positioned to serve as the gatekeeper of the declarative memory system. To detect stimulus familiarity rapidly, it would be more efficient to rely on locally stored information than to retrieve information stored in other brain areas.

Where is the entorhinal cortex located in the brain?

The entorhinal cortex (plural: cortices) (a.k.a. Brodmann area 28) is located in the mesial temporal lobe and acts as the interface between the hippocampus and the neocortex.
